Low Power 5V 1,000kbps RS232 Transceivers  
General Description  
Features  
The ZT232F series devices are +5V powered EIA/TIA-232 and  
CCITT V.28/V.24 communication interfaces with low power re-  
quirements. These transceivers consist of two line drivers, two  
line receivers and the proprietary switch-capacitor regulated  
voltage converters. The ZT310F and ZT312F feature a low power  
shutdown mode which draws as little current as 1μA typical with  
receiver outputs tri-stated and in wake-up. These devices operate  
from a single +5V power supply at the guaranteed high data rate  
of 1,000k bits/sec with enhanced electrostatic discharge (ESD)  
protection in all RS232 I/O pins exceeding 15kV ꢀHB.

Absolute Baximum Ratings  
Storage Considerations  
These are stress ratings only and functional operation of the  
device at these ratings or any other above those indicated in the  
operation sections of the specifications is not implied. Exposure  
to absolute maximum rating conditions for extended periods of  
time may affect reliability.  
Storage in a low humidity environment is preferred. Large  
high density plastic packages are moisture sensitive and  
should be stored in Dry Vapor Barrier Bags. Prior to usage,  
the parts should remain bagged and stored below 40°C and  
60%RH. If the parts are removed from the bag, they should  
be used within 168 hours or stored in an environment at or  
below 20%RH. If the above conditions cannot be followed,  
the parts should be baked for 12 hours at 125°C in order to  
remove moisture prior to soldering. Zywyn ships product in  
Dry Vapor Barrier Bags with a humidity indicator card and  
desiccant pack. The humidity indicator should be below  
30%RH. The MSL of this product is 3.

Proprietary Switch-Capacitor Regulated Voltage Con-  
verter  
effect the serial port and even subject it to transients that could  
potentially damage the transceiver itself.  
Different from other suppliers, Zywyn uses a patent pending  
switch-capacitorvoltage-controlledsourceandsinkcurrentgen-  
erators design to provide powerful bipolar voltages to maintain  
compliant EIA/RS232 levels regardless of power supply fluctua-  
tions.Thedesignconsistsofaninternalregulatedoscillator,atwo  
phase clock cycling, regulated complementary BOS switches,  
fast switching diode and switch capacitors.  
The RS232 transceiver is usually routed from the serial port  
connector to the transceiver IC through the metal trace on the  
printed circuit board. This trace will have some small amount  
of resistance that will add some protection in terms of limiting  
transient current to the IC. ꢀowever for added voltage protec-  
tion, transient voltage suppressors (TVS) or transzorbs, which  
are back-to-back diode arrays clamp, are usually necessary to  
protect the serial port circuity.  
The switch capacitor bi-directional current generators operate  
withZywyn’sproprietarysmartlyregulatedcomplementaryBOS  
switchesandfastswitchingdiodefromitsproprietaryhighvoltage  
processtechnology.Theefficiencyofthesebi-directionalcurrent  
generatorsiswellover70ꢁ.Theswitchingfrequencyisgenerated  
by an internal oscillator and regulated by the current loads. The  
switch capacitor pump design delivers higher negative bucked  
voltage than the positive boosted voltage to achieve a balanced  
voltage controlled source and sink current generators resulting  
a balanced bipolar voltage supplies to the chip.  
To further reduce cost within their system, more engineers are  
requiring higher ESD tolerances from the transceiver ICs them-  
selves without having to add costlyTVS circuitry. Zywyn's RS232  
transceiversincludesbuilt-intransientvoltagesuppressionwhere  
external ESD circuitry is not necessary to meet the BIL-STD-883,  
Bethod3015,umanHodyBodelandtheEN61000-4-2Air/Con-  
tact Discharge tests.  
The ꢀuman Hody Bodel has been the generally accepted ESD  
testing method for semiconductors. This test is intended to  
simulatethehumanbody’spotentialtostoreelectrostaticenergy  
and discharge it to an integrated circuit upon close proximity or  
contact. This method will test the IC’s capability to withstand an  
ESD transient during normal handling such as in manufacturing  
areas where the ICs tend to be handled frequently.  
With its unique proprietary design technique, Zywyn’s interface  
productseriesprovideabetterpowerefficient,stableandcompli-  
ant EIA/RS232 levels with superior low power consumption.  
Controlled Enable and Power-Down  
EN61000-4-2 is used for testing ESD on equipment and systems.  
Forsystemmanufacturers,theymustguaranteeacertainamount  
ofESDprotectionsincethesystemitselfisexposedtotheoutside  
environment and human presence. EN61000-4-2 specifies that  
the system is required to withstand an amount of static electric-  
ity when ESD is applied to exposed metal points and surfaces of  
the equipment that are accessible to personnel during normal  
usage. The transceiver IC receives most of the ESD current when  
the ESD source is applied to the connector pins.  
The ZT310F and ZT312F both feature an enable input, which  
allows the receiver outputs to be either tri–stated or enabled.  
This can be especially useful when the receiver is tied directly to  
amicroprocessordatabus. FortheZT310F, enableisactivelow, in  
whichalogicIGꢀ appliedtotheOFFpinwillenablethereceiver  
outputs. For the ZT310F, enable is active high in which a logic  
ꢀIGꢀ applied to the EN pin will enable the receiver outputs.  
ZT310FandZT312Fhavealow-powershutdownmodecontrolled  
by the ON/OFF pin for the ZT310F and the SꢀDN pin for the  
ZT312F. During shutdown the driver output and the switch-ca-  
pacitor regulated voltage converter are disabled with the supply  
current falls to less than 1μA.  
There are two methods within EN61000-4-2, the Air Discharge  
method and the Contact Discharge method. With the Air Dis-  
charge Bethod, an ESD voltage is applied to the equipment  
under test through air, which simulates an electrically charged  
person ready to connect a cable onto the rear of the system and  
the high energy potential on the person discharges through an  
arcing path to the rear panel of the system before he or she even  
touches the system. The Contact Discharge Bethod applies the  
ESDcurrentdirectlytotheEUT.Thismethodwasdevisedtoreduce  
the unpredictability of the ESD arc. The discharge current rise  
time is constant since the energy is directly transferred without  
the air-gap arc inconsistencies.  
ZT312F includes a wakeup function that enables both receivers  
during a shutdown state. With only the receivers active during  
the shutdown state, the devices draw 5-10μA of supply current.  
A typical application is when a RS232 cable is connected or when  
the peripheral is enabled such as a modem, the devices will au-  
tomatically become active again. After the supply voltage to the  
ZT312F reaches +5.0V, the SꢀDN pin can be disabled, taking the  
ZT312F out of the shutdown mode. All receivers that are active  
during shutdown maintain 500mV (typ.) of hysteresis.

RS232 Signal Characteristics  
The charge pump voltage converter efficiently converts the  
necessary voltage for the driver's output transistors so that the  
RS232 output is close to the ideal rail voltage of 10V.  
ThereceiversconvertRS-232inputsignalstoinvertedTTLsignals.  
The inputs have a typical hysteresis margin of 500mV in order  
to account for signal degradation caused by system interfer-  
ence and other noise related disturbers. This ensures that the  
receiver is relatively immune to noisy transmission lines. The  
input thresholds are 0.8V minimum and 2.4V maximum, which  
are within the TIA/EIA-232 requirements. The receiver inputs are  
also protected against voltages up to 25V. Should an input be  
leftunconnected,a5kohmpulldownresistortogroundwillforce  
the output of the receiver to a high state.  
While loaded with a typical RS232 load, the driver's output level  
only drops 0.2V from its open circuit voltage. Zywyn's low-drop  
driver circuitry working with its efficient voltage regulator allows  
superior line driving capability while meeting the requirements  
of TIA/EIA-232-E.  
The drivers are inverting transmitters, which acceptTTL or CBOS  
inputsandproducestheRS-232compliantsignalsthatisinverted  
relativetotheinputlogiclevels.TypicallytheRS232outputvoltage  
swing is 6V. Even under the worst case loading conditions of  
3kohms and 2500pF, the output is guaranteed to be 5V, which  
adheres to the RS232 standard specifications. The transmitter  
outputs are protected against infinite short-circuits to ground  
without degradation in reliability. The instantaneous slew rate  
of the transmitter output is internally limited to a maximum of  
30V/μs in order to meet the TIA/EIA-232-E requirements.
